Jonathan Hsieh commented on HBASE-8372:
---------------------------------------
Currently, there are none of these hypothetical edits in our unit tests -- if
the did exist today, any attempts would have failed. This patch only widens
the possible places edits can be done but does not introduce the situations you
mention. If can happen somewhere, this means our unit tests are insufficient,
and we should add coverage.
I think it would be appropriate to add that functionality if/when we need it.
If you want me to add it now, please provide a scenario where this problem can
happen today. If a reasonable scenario is described, I'll file a
follow-on-jira to add the unit tests to cover this.
